This is the prime spot for encountering green sea turtles, which graze on seagrass beds near the jetty and cruise through the crystal-clear shallows. The protected northern lagoon is calm, easy to wade into from the beach, and perfect for beginners — you can stand up whenever you need a break. Parrotfish, surgeonfish, and wrasse swarm the coral gardens, and blacktip reef sharks are occasionally spotted gliding along the sandy bottom. The island's rainforest backdrop and the turquoise water create a postcard setting that feels remote yet remains the most accessible Great Barrier Reef experience from Cairns.","beginner","published",{"name":58,"amplitude":74,"phase":90,"latitude":22,"model":106,"epoch":107},[59,60,61,62,63,64,65,66,67,68,69,70,71,72,73],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[75,76,77,78,79,80,81,82,83,84,85,86,87,88,89],0.026054077957643848,0.01847871504946906,0.31120792360533145,0.08832826278730357,0.5377835819878392,0.004747167594609563,0.011184450669996833,0.007752382305522191,0.18386318873990673,0.15177916748244735,0.08535112484419902,0.02479242983347573,0.006967173756168378,0.31068314791592144,0.035762773194971086,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],319.41404288101836,51.3574305963595,39.459426072866265,299.6379886223655,344.15314595570686,229.18382752835748,5.485234176033182,37.89894936663641,327.6730496386229,12.735975707126011,36.91569335660561,353.6337051906012,333.73183009838533,304.60541527900796,269.4487865357923,"EOT20","1992-01-01T00:00:00Z",[109,115,120,123,126,130,133,137,140,143,146,149,152,155,158,161],{"name":110,"description":111,"severity":112,"season_start":113,"season_end":114},"Stinger Season (Jellyfish)","Stinging jellyfish (including box jellyfish and Irukandji) are present in tropical QLD waters, typically November to May.","warning",5,11,{"name":116,"description":117,"severity":118,"season_start":119,"season_end":119},"Tidal Currents","Outgoing currents between the cay and the reef edge can be strong, especially during falling tides.","caution",null,{"name":121,"description":122,"severity":118,"season_start":119,"season_end":119},"Sharp Coral","Sharp coral formations and reef cuts are present just off the beach; wearing reef shoes is recommended.",{"name":124,"description":125,"severity":118,"season_start":119,"season_end":119},"Sun Exposure","High sun exposure with reflected UV off the water surface; dehydration and sunburn risk.",{"name":127,"description":128,"severity":112,"season_start":129,"season_end":114},"Marine stingers (jellyfish)","Stinger jellyfish (box jellyfish and Irukandji) are present in these waters from November to April.
